Purpose: Crawl Lab is a free SEO toolbox for analyzing server logs and AI crawler activity.
Log formats: The analyzer supports Apache and Nginx combined or common logs, including compressed .gz files.
Crawl metrics: It reports crawled pages, crawl frequency, wasted crawl budget, and errors seen by bots.
AI crawlers: It detects GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, Amazonbot and other crawlers.
Bot verification: The analyzer verifies crawler authenticity using official IP ranges.
Local processing: All processing runs in the browser and log files and IP addresses never leave the user's machine.
Privacy: Crawl Lab describes the analyzer as RGPD-safe because files are not uploaded or stored.
Scale: The tool reads files in streaming mode and can analyze several gigabytes or a full month of logs without a server-imposed size limit.
No account: The analyzer requires no registration or account.
Audience: The product is aimed at technical SEO practitioners working on SEO and generative-engine visibility.
Upcoming tools: Crawl Lab lists an llms.txt generator and an AI citation audit as coming soon.
Limitations: Log analysis proves what crawlers fetched but does not show whether pages were indexed or how they rank.
